Naming
The black-browed fulvetta, "Alcippe grotei", is sometimes considered to be conspecific with mountain fulvetta, but the two forms differ in morphology and vocalisations, and are separated altitudinally. Black-browed fulvetta occurs primarily below 400 m, and mountain fulvetta above 900 m.Behavior
Mountain has a "yi-yuii-uwee-uwee" song, whereas black-browed's is "yu-chi-chiwi-chuwoo, yu-uwit-ii-uwoo".References:
